I have the DG "two-fer" Ray mentioned.  Bernstein and the Vienna
Philharmoniker were fabulous in these recordings (although I'll admit
it was the price (19.99?) that made me bite) and I never went pursuing
another recording thereafter.  Number 4 in d minor, my personal favorite,
is brilliant and I am very happy it didn't cost an arm and a leg for the
complete set of Schumann's symphonies.
